Bug 13706: New script dedup_authorities.pl

This script allow to deduplicate authorities automatically.

Script is in misc/maintenance/

It works this way:
 1) authorities are fetched from the database. You can limit fetched
 results by authtypecode, or directly by specifying WHERE clause
 2) for each authority:
  2.1) build a Zebra query using the 'search_form' for the heading
  2.2) run the query, retrieve the results
  2.3) among duplicates, choose the one we want to keep (use
  --choose-method option).
  2.5) use C4::Authorities::merge to merge authorities
 3) delete the merged authorities

Use --help for more informations on options

To be done:
1 - Move to module and cover with tests
2 - Add option to only merge unused authorities
3 - Expand 'ppn' option to be 'control-number' option and allow specifying
field
4 - More?

1 & 2 I will attempt - 3 & 4 may be future enhancements
